COMBINED ANGLE-BAR NUT-LOCK AND BASE-PLATE FOR RAIL-JOINTS.

Specification of Letters Patent.

Patented June 2, 1908.

Application filed. SeptembenlZ, 1907. Serial No. 392,486.

To all whom it may concern:

Be it 1: nown that I, HENRY N. Nonrnorr, a citizen of the United States,residing atthe city of Columbus, county of Franklin, State of Ohio, haveinvented an Improvement in a Combined Angle-Bar N u't-Lock and Base-Plate for Rail-Joints, and do hereby declare application of same, aswill be hereinafter,

more fully described and particularly pointed out in the claims and'theaccompanying drawing. 5

in the accompanying drawing the reference characters indicate same partsof the invention in the several views.

Figure 1 represents a rail-joint with the usual splice-bars, bolts,nuts, and cross-ties, showing a front elevation of the angle-barnut-lockand base-plate in position and the manner of fastening the same. Fig. 2represents a detail; sideielevation of a rail-joint with the anglebar-nut-lock in-position. Fig. 3 is a sectional'view taken on a planeindicated by the line aa. Fig. 4 represents a 'detail elevation of thebase-plate, showing the location of the holes for the admission of thefastenin spikes to the cross-ties. Fig. 5 is a sectiona view of thebase-plate, taken on a plane indicated by the line b-b.

In the embodiment of my invention, I employ in combination with any kindand shape if rail-joint-bolt-nuts, a sin le continuous ngle-bar A, madeof meta cast, rolled, forged or stem ed and consistinm of the vertheangle-piece This angle-bar A, when laced in right position is located onthe rai -joint (as shown in Figs. 2 3) on the same side with thebolt-nuts, running through the entire length of the railjoint in onecontinuous piece and is shaped in such a way, that the vertical leg a ofthe angle-bar A, lies close to the face of the splice-bar andthe'angle-piece b lies upon the foot of the rail, forinin a ood fittingconnection between the splicear, rail and the angle-bar A.

The vertical leg a of the angle-bar A is provided on the upper edge withangular slots 0 for the purpose of forming a receptacle for thebolt-nuts; the intermediate parts of the vertical lega, situated betweensaid angular slots 0 constituting locks 0, these locks c standing withtheir vertical sides parallel to the vertical sides of the bolt-nuts arebound to hold and keep the bolt-nuts secure in position, thereforepreventing the said bolt-nuts from turning or moving absolutely.

The angle-bar A is not limited in lengthto the len th of the rail-jointit may run over the rai -joint in any convenient len 'th; in height theangle-bar A is limited .to t 1e section of the rail or rail-joint beingused.

The vertical leg (1 of the angle-bar A does not reach through the entirelength up to the head of the rail, only the center part of said verticalleg a situated between the two center' slots 0 forming the center lock 0is provided with an upward extension d nee y abutting with theprojection e under the head of the rail; the parts of the vertical leg alo catedto the right and left of said upward eX- tension at reachinghigh enough to cover the part of the bolt-nuts necessary to keep themsecure in position. The vertical leg a is further provided on the outerside with a stiffening rib f, this stiffening rib fstarts on the upperend of said vertical leg a terminating just above the lower end of theslots 0 reinforcing the intermediate locks 0 through the entire lengthof said vertical leg at; on the angle point the angle-bar A is rovidedwith a orizontal lip :g acting as a iller in the space at thetermination of the splice-bar and the foot of the rail.

Both ends of angle-piece b of the angle-bar A are further provided withprojections 7b, the center part of said angle-piece b has a similarprojection i with slots cut in, which slots 7' serve the purpose ofreceiving the spikes of the rails; these slots 9' are only large enoughto allow the spikes to rest in.

The end projections h and the center projections i are flattened ontheir tops so as to form a solid base for the head of the fasteningspikes.

The plate B Fig. 4, being an integral part of the device consists of aplate of uniform thickness, made of metal, cast, rolled or stamped,shaped rectangularly and is provided near the ends with holes 70 and Z,these holes kand l are square and serve the purpose of allowing to passthe fastening spikes through, to be embedded in the cross-ties. I

The holes 7c placed on the front of the plate B, have to correspond withthe slots in the center projection i of the angle-piece b, the holes Zon the back end of the plate may be placed in any suitable space; theparallel distance between the holes is and l to be govterned by thesection of the base of the rail, the late B is to be ap lied to.

Tfleplate B is providiad on one of its sides with a rib m, this rib m,when the plate B is placed in right position stands parallel to theangle-bar and with its inner side fitting snugly to the lower art of thecentral projection i of said ang e-bar A acts as a stop against anyforward sliding motion of the angle-bar A; it can be clearly seen fromthe fore oing described arrangement, that once the olt-nuts theangle-bar and plate are fastened in place, any moving or displacing ofthe angle-bar is practically prevented; in upward direction, through thelower end of t je slots c and by, is upward extension (Z of theangle-bar A against the rail-head; laterally both ways,- through theslots 0 or looks c and the bolt-nuts therein and through the horizontalprojections h on both ends and the center rojection'i on the foot of theanglebar and t e corresponding spikes driven through the baseplate B inthe underlying cross-ties; and in a downward direction,

1 throng through the horizontal rib m on the front end of the j late Band the fastening spikes driven h the plate B in the underlyingcrossties; therefore the angle-bar A safely secured from moving inwhatever direction, is bound to prevent the bolt-nuts from turning ormoving; consequently the purpose of the device for a safe, simple andabsolute lock for railjoint-bolt-nuts is accomplished.

Although I have s ecially described my invention with regar s to theconstruction and relative arrangement of the several elewhat I claim asnew and useful and desire to procure by Letters Patent is;

1. A lockin bar for rail joints comprising a longitudinal y extending.late having lockin recesses in its upper e ge adapted to receive thenuts, end flan es and a central flange extending outward y from thelower edge of the plate to provide means for securing the said plate tothe ties and a centrally located member projecting upwardly from theupper edge of the plate to engage the rail flange and said plate alsohaving stren thening ribs extending longitudinally of the plate and inline with the locking recesses substantially as described.

2. A lockin bar for rail joints comprising a longitudinal y extendingCpglate having lock-' ing recessesin its upper e e adapted toreceive thenuts, end flan es and a central flange extending outwarifly from thelower edge of the plate to provide means for securing the said plate tothe-ties and a centrally located member projecting upwardly from theupper edge of the plate to engage the rail flange and saidplate alsohaving strengthening ribs extending longitudinally of the plate and inline with the locking'recesses, a plate having a 1projecting ribextending upwardly on one 0 means for holding the locking bar secure inposition substantially as described.
